802.x is a set of IEEE standards
for defining networking protocols
for the definition of fixed and wireless LAN
and MAN protocols which include the physical layer and
link layer of a LAN. Physical layers include both wired
and wireless, as in 802.11 series.
ActiveX is a set of technologies from Microsoft
that enables interactive content for the World Wide
Web. Before ActiveX, Web content was static, 2-dimensional
text and graphics. With ActiveX, Web sites come alive
using multimedia effects, interactive objects, and sophisticated
applications that create a user experience comparable
to that of high-quality CD-ROM titles. ActiveX provides
the glue that ties together a wide assortment of technology
building blocks to enable these "active" Web
sites. ActiveX is comparable to Sun
Microsystems' Java only its a technology developed
and owned by Microsoft.
Here's a page that further explains ActiveX
and its benefits for Web interactivity.
Analog vs. Digital
In communication and electronics systems, data is
transmitted from one point to another by means of these
electronic signals. These signals are divided up into
analog and digital. Amplitude modulation (AM), and frequency
modulation (FM) are both Analog transmission schemes.
Analog signals are, "continuously varying electronic
waves that may be transmitted over a variety of media
depending on frequency." Digital signals contain
a "sequence of voltage pulses that may be transmitted
over a wire medium."
Check Google for more info on the
difference between analog vs. digital.
Anonymous File Transfer Protocol allows the public
to log into an FTP server with a common login (usually
"ftp" or "anonymous" and any password
(usually the person's e-mail address is used as the
password). Anonymous FTP is beneficial for the distribution
of large files to the public, avoiding the need to assign
large numbers of login and password combinations for
Anonymous FTP is a type of FTP. It allows website visitors
to download information from a website without entering
a username and password, thus the name "Anonymous FTP".
Regular FTP, in contrast, requires a username and password.
You might need Anonymous FTP if you plan to distribute
software, images, PDF documents, or other types of files
to your website visitors.
Acronym for the American National Standards Institute
(ANSI). Founded on October 19, 1918, the American National
Standards Institute is a private, non-profit organization
(501(c)3) that administers and coordinates the U.S.
voluntary standardization and conformity assessment
system. The Institute's mission is to enhance both the
global competitiveness of U.S. business and the U.S.
quality of life by promoting and facilitating voluntary
consensus standards and conformity assessment systems,
and safeguarding their integrity.

A small Java program that can be embedded in an
HTML page. Applets differ from full-fledged Java applications
in that they are not allowed to access certain resources
on the local computer, such as files and serial devices
(modems, printers, etc.), and are prohibited from communicating
with most other computers across a network. The current
rule is that an applet can only make an Internet connection
to the computer from which the applet was sent.
A software program for finding files stored on Anonymous
FTP sites. You need to know the exact file name or a
substring of the file, though, to use Archie. Archie
and other Internet / Web utilities can be downloaded
from C|Net's Download.com.
ARPAnet stands for Advanced Research Projects Agency
Network. The precursor to the Internet. Landmark packet-switching

ASCII is the acronym for American Standard Code
for Information Interchange. The American Standard Code
for Information Interchange is a standard seven-bit
code that was proposed by ANSI in 1963, and finalized
in 1968. Other sources also credit much of the work
on ASCII to work done in 1965 by Robert W. Bemer (www.bobbemer.com).
ASCII was established to achieve compatibility between
various types of data processing equipment. Later-day
standards that document ASCII include ISO-14962-1997
ASCII, pronounced "ask-key", is the common
code for microcomputer equipment. The standard ASCII
character set consists of 128 decimal numbers ranging
from zero through 127 assigned to letters, numbers,
punctuation marks, and the most common special characters.
The Extended ASCII Character Set also consists of 128
decimal numbers and ranges from 128 through 255 representing
additional special, mathematical, graphic, and foreign

An e-mail Auto-Responder automatically sends a generic
or pre-written reply to anyone that e-mails the e-mail
address assigned with an Auto-Responder. It's like a
voice mail message for your e-mail. For example, if
someone sends a question to email@example.com, you can
send them a generic auto-response that thanks them and
assures them you will then back write soon.
AVI is an early Microsoft video file format, that
stands for Audio Video Interleave. AVI was one of the
very first recognized audio-video standard formats for
the PC and the Web. AVI files require a special audio-video
player designed specifically for
viewing or listening to audio-video content. Such players
include Microsoft's own Windows
Media Player or Real Networks'

A Backbone is a larger transmission line (OC3, OC2,
OC1) that carries enormous amounts of data (audio, video,
voice) gathered from smaller lines that interconnect
a) At the local level, a Backbone is a line or set of
lines that local area networks connect to for a wide
area network connection or within a local area network
to span distances efficiently (for example, between
b) On the Internet or other wide area network, a backbone
is a set of paths that local or regional networks connect
to for long-distance interconnection. The connection
points are known as network nodes or telecommunication
data switching exchanges (DSEs).
A Backbone provider is an organization that supplies
Internet access (high-speed transmission lines that
connect users to the Internet) to Internet
Service Providers (ISPs) which then offer individual
Internet access connections to customers. Backbone providers
supply ISPs with the cake (T3, T1 lines) which, in turn,
cut up the cake and resell and connect individual pieces
(DSL, dial-up) to its customers.
BBS stands for Bulletin Board System. A BBS is a
computerized meeting and announcement system that allows
people to carry on discussions, upload and download
files, and make announcements without the people being
connected to the computer at the same time. In the early
1990's there were many thousands (millions?) of BBS?s
around the world, most are very small, running on a
single IBM clone PC with 1 or 2 phone lines. Some are
very large and the line between a BBS and a system like
AOL gets crossed at some point, but it is not clearly
A Blog is basically a journal that is available
on the web. The activity of updating a Blog is "blogging"
and someone who keeps a Blog is a "blogger."
Blogs are typically updated daily using software that
allows people with little or no technical background
to update and maintain the Blog. Postings on a Blog
are almost always arranged in cronological order with
the most recent additions featured most prominantly.
For example of a blog, check out Steve Jobs' personal
blog at http://justonemorething.com/.
Bps is the acronym for "bits per second",
which is the standard measure of data transmission speeds.
A "bit" represents the smallest unit of data
in a computer; 8 bits make up one byte, which can represent
a character like "A" or "3". Usually
you'll hear us talk about not bps but Kbps, for kilobits
per second. If you have a 28.8 Kbps modem, it means
that your modem can transmit at speeds up to 28,800
bits of information per second.
A transmission facility having a bandwidth sufficient
to carry multiple voice, video or data channels simultaneously.
Each channel occupies (is modulated to) a different
frequency bandwidth on the transmission medium and is
demodulated to its original frequency at the receiving
end. Channels are separated by ìguardbandsî
(empty spaces) to ensure that each channel wonít
interfere with its neighboring channels. This technique
is used to provide 50 CATV channels on one coaxial cable.
In other words, really fast!
Software which lets you view material designed for

The unit of data storage and transmission in computers.
A byte is usually considered the code for a single character.
The number of bits in a byte varies among computer systems.
We usually think of a byte as being 8 bits long. The
English Latin alphabet has 52 characters (upper and
lower case) and computers commonly also use punctuation
marks and a few special characters such as the period,
exclamation mark, slashes, equal sign, tilde, ampersand,
dollar symbol, pound sign, percent mark, asterisk, plus
sign, and carriage return. Including punctuation mark
and special characters, we need approximately 100 unique
Each bit can exist in only two states, 0 or 1. Thus,
a 6 bit word can define only 64 characters, a 7 bit
word can define 128 characters, and an 8 bit word can
define 256 characters. If one bit is used to check the
integrity of the entire byte, then we need at least
an 8 bit byte (or "word") for common computer
A section of a computer's memory which retains recently
accessed data in order to speed up repeated access to
the same data. Your computer and browser use cache memory
to load Web pages more quickly. Your ISP also uses a
cache for this purpose. If you ask your computer to
view a page, and it finds the page in the cache, it
will read the cached page instead of the page from the
Internet, unless you reload the page.
To further explain Cache, the term refers to: 1) a region
of computer memory where frequently accessed data can
be stored for rapid access; or 2) a optional file on
your hard drive where such data also can be stored.
Examples: Inernet Explorer and Netscape have options
for defining both memory and disk cache. The act of
storing data for fast retrieval is called "caching".
The name given to a place or page in a Web site
or online service where people can "chat"
with each other by typing messages which are displayed
almost instantly on the screens of others who are in
the "chat room." Chat rooms are also called
"online forums." In order to chat in a Chat
Room you need to use a chat room program that you access
with your Web browser.
Another explanation of a Chat Room would be a place
on the Internet where people go to "chat"
with other people in an online "room". Chat
Rooms are usually organized by topic. For example in
a California Chat Room you would expect that most of
the participants in the room are probably from California.
When you're in a Chat Room you can view all of the conversations
taking place at once on your screen. You can also get
into a private chat room where only you and one or two
others may converse back and forth. This can be an inexpensive
way to keep up with friends and relatives who are online.
Chat Rooms are similar to Instant Messaging
(IM) but the difference is in the software. Chat
Room software is stored on an Internet server and is
accessible through a Web browser,
where an IM software program is stored on your local
computer. You need to launch an IM program in order
to IM someone. Both require connection to the Internet.
CGI is the acronym for Common Gateway Interface,
a set of rules that describe how a Web Server communicates
with another piece of software on the same machine,
and how the other piece of software (the 'CGI program')
talks to the web server. Any piece of software can be
a CGI program if it handles input and output according
to the CGI standard. Usually a CGI program is a small
program that takes data from a web server and does something
with it, like putting the content of a form into an
e-mail message, or turning the data into a database
query. CGI "scripts" are just scripts which
use CGI. CGI is often confused with Perl, which is a
programming language, while CGI is an interface to the
server from a particular program. Perl is an application
of CGI, as well as MIVA, Python, PHP3, and other scripting
CGI-Bin is the most common name of a directory on
a web server in which CGI programs are stored. The 'bin'
part of 'cgi-bin' is a shorthand version of 'binary',
because once upon a time, most programs were referred
to as 'binaries'. In real life, most programs found
in cgi-bin directories are text files -- scripts that
are executed by binaries located elsewhere on the server.
While most programs using CGI are stored in this directory,
it is not a requirement for using CGI. See Also: CGI
A misleading name for a type of application that
runs on a local computer or workstation. For example,
Outlook Express is an email client that enables you
to send and receive email.
A type of dedicated server that involves your your
own machine and server administration. A leased
server, on the other hand, involves renting a server
from JTLnet and includes basic OS configuration and
COMchannel is a web-based email service from JTLnetT
Communications. To access your mail via COMchannel,
point your browser to www.comchannel.com.
Type in your username and password to view your email.
If you have an IMAP account, you can access all messages
and folders using COMchannel. POP users, however, can
only see new mail messages that have not yet been downloaded
onto their computer at home or work.
A Cookie is a piece of information sent by a Web
server to a user's browser. (A Web server is the computer
that "hosts" a Web site, and responds to requests
from a user's browser.) Cookies may include information
such as login or registration identification, user preferences,
online "shopping cart" information, etc. The
browser saves the information, and sends it back to
the Web server whenever the browser returns to the Web
site. The Web server may use the cookie to customize
the display it sends to the user, or it may keep track
of the different pages within the site that the user
accesses. Browsers may be configured to alert the user
when a cookie is being sent, or to refuse to accept
cookies. Some sites, however, cannot be accessed unless
the browser accepts cookies.
Cron Jobs (or just Cron) is the ability to run programs
based on the system clock. Most hosting companies allow
up to one operation per day between the hours of 12:00
a.m. and 8:00 a.m. Cron can also be explained as server
commands for scheduling jobs to be executed sometime
in the future. A Cron is normally used to schedule a
job that is executed periodically - for example, to
send out a notice every morning. It is also a daemon
process, meaning that it runs continuously, waiting
for specific events to occur.
CSS stands for Cascading Style Sheet. A CSS is used
to assign a style to a web page, in particular, styles
for fonts, font colors, font sizes, links, link colors,
text navigation, and the like, that go into the web
page than could be provided by raw HTML or text. CSS
code resides within the <HEAD> </HEAD> tags
of the HTML code or can be a separate file altogether.
The advantages of using a CSS file for your website
is consistency of design and you only have to write
one CSS file for your entire website. Here's an example
of a CSS file and CSS code - www.jtlnet.com/css.css.
This term was coined by author William Gibson in
his science fiction novel Neuromancer.
Cyberspace is currently used to describe the whole range
of information available through computer networks.
Cyberspace refers to the various information resources
that are available through computer networks and the
Internet, as well as to "communities" which
have developed through their common use of such resources,
and to the culture which is developing in such electronically
connected communities. May also be used to distinguish
the physical world from the digital, or computer-based
A collection of organized information in which a
computer can easily display and select different fields
of data. You can think of a database as an electronic
filing system. You can include anything from birthdays
to travel itinerary in a database. MySQL is one of the
database management system we feature at JTLnet.
Common database software for creating, manipulating,
viewing, and updating database "data" include
Microsoft SQL, Microsoft
Access, FileMaker (for
computers), and Oracle.
Data Transfer (or Data Download) refers to the amount
of information (measured in Megabytes, or Mb) transferred
from our servers here at JTLnet to your website visitors.
For example, you are requesting about 1/20th of a MB
right now because you clicked on this page. Typically,
the more people that visit your site, or the larger
the files that people request from your site, the more
data transfer you will need. Media-intensive websites
in particular can require large amounts of data transfer.
A Dedicated Line is a telephone wire that is run
from one location, such as your home, to another location,
such as your office. A dedicated line is not switchable.
It may only be used to communicate between the two designated
locations. A switched line (normal telephone line) can
be connected to different locations by a switching mechanism
such as a telephone dial. Types of Dedicated Lines include
T-3, T-1 or ISDN data connections used to transfer data
between a client and a server.
A dedicated server is a computer that only runs
one type of server software, and is usually constructed
according to the user's specifications. Dedicated servers
are typically used for websites that have high traffic,
and need many resources and much processing power. When
your site is hosted on a Dedicated Server, the hosting
company or Internet service provider
(ISP) provides a Windows NT
or UNIX / Linux server and connects
it to a high-speed Internet network. All you have to
do is develop content for your site and install the
necessary applications on the server.
DHTML is the acronym for Dynamic Hyper-Text Markup
Language. DHTML is HTML on steroids.
Web authors today face significant challenges when making
their Web pages interactive. The static nature of HTML
pages limits their creative choices, and interactive
components can be difficult to build. Dynamic HTML gives
authors creative control so they can manipulate any
page element and change styles, positioning, and content
at any time -- not only when the page is loaded. Dynamic
HTML adds more elegance to basic HTML. With DHTML, you
can make changes without causing the whole screen to
redraw. So, for example, in a DHTML site, users can
roll over a menu and see the choices change color, or
they see one graphic to turn into another graphic. A
good DHTML programmer can write code that will be 'friendly'
to all browsers and types of computers.
A digital certificate is an electronic means of
establishing your credentials when doing business or
other transactions on the Web. It is issued by a certification
authority (CA). It contains your name, a serial number,
expiration dates, a copy of the certificate holder's
public key (used for encrypting and decrypting messages
and digital signatures), and the digital signature of
the certificate-issuing authority so that a recipient
can verify that the certificate is real. Some digital
certificates conform to a standard, X.509. Digital certificates
can be kept in registries so that authenticated users
can look up other users' public keys.
A Digital Certificate is a digital representation of
information which at least (1) identifies the certification
authority issuing it, (2) names or identifies its Subscriber,
(3) contains the Subscriber's public key, (4) identifies
its operational period, and (5) is digitally signed
by the certification authority issuing it. A Digital
Certificate is a data structure used in a public key
system to bind a particular, authenticated individual
to a particular public key.
A unit of organization for storing information on
a computer. Within a directory, you can store subdirectories
and files. Directories and subdirectories are analogous
to drawers in a filing cabinet. The top directory, or
home directory, refers to the directory you log into.
The current directory, or working directory, refers
to the directory you are working in presently.
A Directory can also be defined as a special kind of
file used to organize other files into a hierarchical
structure. Directories contain bookkeeping information
about files that are, figuratively speaking, beneath
them. You can think of a directory as a folder or cabinet
that contains files and perhaps other folders. In fact,
many graphical user interfaces use the term folder instead
A Domain Alias allows additional domain names to
point to a common website. This feature is useful when
you want users to be able to access the same web site
through a number of different addresses. An example:
Acme Corporation registers two domain names, A and B.
It places its web site at A, and makes B a domain alias
of A. Whenever someone types in the address of domain
B, they are automatically redirected to domain A.
A Domain Mirror creates two separate copies of your
website, each on a different server. This is ideal for
high-profile sites that need a 100% uptime guarantee. Website
mirrors also provide convenient management of heavily
trafficked websites. For example, you could direct East-Coast
users to one server, and West-Coast users to another
The unique name that identifies an Internet site.
Domain Names always have 2 or more parts, separated
by dots. For example, www.jtlnet.com,
or www.xyz.net. The part on the left is the most specific,
and the part on the right is the most general. A given
machine may have more than one Domain Name but a given
Domain Name points to only one machine. This means that
the Domain Names www.domain.net, mail.matisse.net, and
workshop.matisse.net can all refer to the same machine,
but each Domain Name can refer to no more than one machine.
Usually, all of the machines on a given Network will
have the same thing as the right-hand portion of their
Domain Names (matisse.net in the examples above). It
is also possible for a Domain Name to exist but not
be connected to an actual machine. This is often done
so that a group or business can have an Internet e-mail
address without having to establish a real Internet
site. In these cases, some real Internet machine must
handle the mail on behalf of the listed Domain Name.
The act of registering an Internet Domain Name is
with interNIC, the governing body of domain names. An
Internet domain name is an organization's unique name
combined with a top level domain name (TLD). For example,
arishost.com is the domain name of this registrar. Following
are the top level domains. The .edu, .mil and .gov domains
are traditionally U.S. domains. At the end of 1999,
more than six million domain names were registered.
Needless to say, many more are expected.
Before registering a Domain, you need to first research
to find out if it is available. www.whois.sc
is the best website for researching available domain
names. If your desired Domain is available, you can
register it at the first and the best Domain registrar,
Network Solutions, at www.networksolutions.com.
DSN is short for Domain Name System or Domain Name
Server. This is a system that using a database, translates
your IP address or Internet Protocol address into an
easy to remember name such as, www.jtlnet.com.
So essentially, it makes it to where you don't have
to remember a long series of numbers, but rather an
actual name of a place. The DNS server's main job is
to bind the IP address to a domain name. It can also
be referred to as a name server, or domain name server.
Whether you are using ftp, gopher, or http (web) these
all require IP addresses.
Asymmetric Digital Subscriber Line is a method for
moving data over regular phone lines. An ADSL circuit
is much faster than a regular phone connection, and
the wires coming into the subscriber's premises are
the same (copper) wires used for regular phone service.
An ADSL circuit must be configured to connect two specific
locations, similar to a leased line.
A commonly discussed configuration of ADSL would allow
a subscriber to receive data (download) at speeds of
up to 1.544 Megabits per second, and to send (upload)
data at speeds of 128 kilobits per second. Thus the
'Asymmetric' part of the acronym.
Another commonly discussed configuration would be symmetrical:
384 kilobits per second in both directions. In theory
ADSL allows download speeds of up to 9 megabits per
second and upload speeds of up to 640 kilobits per second.
ADSL is often discussed as an alternative to ISDN, allowing
higher speeds in cases where the connection is always
to the same place.
The term used to describe how an IP
Address is dynamically assigned to computers as
and when needed. Unlike Static IP addresses, the IP
Address is temporary e.g. when you connect to your ISP
using a dial-up connection , you PC or router will be
dynamically assigned an IP address whilst you are on-line.
E-commerce (or electronic commerce) is any business
transaction whose price or essential terms were negotiated
over an online system such as an Internet, Extranet,
Electronic Data Interchange network, or electronic mail
system. It does not include transactions negotiated
via facsimile machine or switched telephone network,
or payments made online for transactions whose terms
were negotiated offline. The end-to-end digital exchange
of all information needed to conduct business. Examples
include EDI transactions, electronic mail, archives,
audit trails, and all forms of records, including graphical
images. Electronic Data Interchange (EDI), Electronic
Funds Transfer, (EFT) and Continuous Acquisition and
Life-cycle Support (CALS).
EFF stands for the Electronic Frontier Foundation
which was founded in July 1990, to assure freedom of

E-Mail is short for electronic mail. It is the official
term for electronic communication in text or HTML format
over the Internet. E-Mail is the transfer of information
from one computer to another, provided that they are
hooked up via some sort of network. E-mail works similarly
to FAXing, but its contents typically get printed out
on the other end only on demand, not immediately and
automatically as with FAX. A machine receiving e-mail
will also not reject other incoming mail messages as
a busy FAX machine will; rather they will instead be
queued up to be received after the current batch has
been completed. E-mail is only seven-bit clean, meaning
that you should not expect anything other than ASCII
data to go through uncorrupted without prior conversion
via something like uucode or bcode. Some mailers will
do some conversion automatically, but unless you know
your mailer is one of them, you may want to do the encoding
E-Mail Aliases allow you to setup as many e-mail
addresses as you would like for your domain. E-mail
aliases are just "aliases" of a POP3 account
within your domain. Aliases can only be setup to direct
firstname.lastname@example.org (Alias) to a POP or forwarding
or the default email account. This means that they will
not be able to point to another domain. You can have
multiple aliases pointing to the same POP3 account.
You can forward any alias email account (which is any
email account that ends with your domain name that is
not defined as a forwarding or pop3 account) to an email
forwarding account, but remember you are limited to
the number of forwarding accounts. Unlimited Alias email
accounts will automatically forward to your default
An Example: say Bill is the president of your business.
He needs alias email addresses email@example.com,
firstname.lastname@example.org be directed to email@example.com
his POP3 email address. President@yourdomain.com and
firstname.lastname@example.org would both be e-mail aliases of
email@example.com and all mail sent to any of these
three e-mail addresses would be directed to the firstname.lastname@example.org
A service that directs e-mail messages sent to one
address to another address. E-mail forwarding is analogous
to call forwarding for telephones. Once your domain
name is active worldwide, you can receive all e-mail
addressed to your domain such as email@example.com,
firstname.lastname@example.org, etc. By default, all e-mail addressed
to your domain will forward to your real e-mail address
(POP3 account) which is email@example.com. For
convenience, specific mail forwarding options are available
if you need specific addresses each to be forwarded
to different addresses on the internet. For example,
e-mail addressed to firstname.lastname@example.org could forward
to an account at AOL, but email@example.com could forward
to a Prodigy e-mail account.
Encryption is the transformation of data into a
form unreadable by anyone without a secret decryption
key. Its purpose is to ensure privacy by keeping the
information hidden from anyone for whom it was not intended,
including those who can see the encrypted data. Encryption
may be used to make stored data private (e.g., data
that is stored on a potentially vulnerable hard disk),
or to allow a nonsecure communications channel to serve
as a private communications channel. Encryption is sometimes
described as the process of converting plain text into
Encryption prevents any non-authorized party from reading
or changing data. The level of protection provided by
encryption is determined by an encryption algorithm.
In a brute-force attack, the strength is measured by
the number of possible keys and the key size. For example,
a Triple-Data Encryption Standard system (3 DES) uses
112-bit or 168-bit keys and, based on currently available
processing power, is virtually immune to brute-force
attacks. Business to Business VPNs (Extranets) share
sensitive data with multiple organizations, so demand
the highest level of security. This requires public
key encryption and/or secure key exchange, both of which
are designed to eliminate the risk of the key becoming
known to an unauthorized party.
Ethernet is a Local-Area Network (LAN)
protocol developed by Xerox Corporation in cooperation
with DEC and Intel in 1976. Ethernet uses a bus or star
topography and supports data transfer rates of 10 Mbps.
The Ethernet specification served as the basis for the
IEEE 802.3 standard, which specifies the physical and
lower software layers. Ethernet uses the CSMA/CD access
method to handle simultaneous demands. It is one of
the most widely implemented LAN standards. A newer version
of Ethernet, called 100Base-T (or Fast Ethernet), supports
data transfer rates of 100 Mbps. And the newest version,
Gigabit Ethernet supports data rates of 1 gigabit (1,000
megabits) per second.
Ethernet is the most popular communication system for
Local-Area Networks (LAN). Each machine
on the network has an Ethernet card connected to the
computer's bus, and to either 10base-T (twisted pair)
or coaxial cable. The computer lab's network is Ethernet.
Another, less popular networking standard is Token Ring.
Ethernet supports "packet switching." Each
Ethernet NIC has a unique address that is attached to
the packets it sends and receives.
More information including a complete history of Ethernet
can be found at www.web-hosting-reviewer.com/glossary/ethernet.html.
An Extranet is a private network that uses the Internet
protocols and the public telecommunication system to
share part of business information with suppliers, vendors,
customers, or other businesses. An extranet can be viewed

What You See Is What You Get. A WYSIWYG word processor,
for example, lets a user work view an on-screen document
as it will appear on the printed page, e.g., with text
in italics appearing on-screen in italics. This approach
to software was pioneered by Xerox Palo Alto Research
Center in the 1970s and widely copied since then, notably
by the Apple Macintosh. WYSIWYG
is extremely effective for structurally simple documents
that are printed once and never worked on again. WYSIWYG
is extremely ineffective for the production of complex
documents and documents that must be maintained and
kept up-to-date over many years. Thus Quark Xpress and
Adobe Frame facilitated a tremendous boom in desktop
publishing while Microsoft FrontPage
and similar WYSIWYG tools for Web page construction
have probably hindered development of interesting Web
Short for eXtensible Markup Language. XML is a programming
language that enables designers to create their own
tags to indicate specific information. The House of
Representatives, for example, has recently issued a
list of XML tags to be used for Web forms on Member
Web sites and other Web sites that send e-mail to congressional
offices. The purpose of these forms is to enable correspondence
management systems (CMS) and other software to easily
identify and process types of information -- such as
name, city, state, zip code, issue, etc. -- which will
help make the software more efficient and more effective.
These tags will help CMS vendors that do not currently
offer the ability to process incoming e-mail provide
